Every poll-interval seconds, the background thread will ensure that the source has num-buffers unprocessed buffers of at most buffer-size openal sound each, and the thread will refill processed buffers as necessary to ensure gapless playback.


The port should yield bytes suitable for OpenAL playback, with the given formatand sample rate of frequency typically Just after the last buffer is queued, the thread will run the at-end-of-loop procedure which returns t if the thread should continue or f if it should stop once openal sound last buffer finishes. You might use the at-end-of-loop function to seek the port back to the beginning of the file to seamlessly openal sound playing back at the beginning of the file when reaching the end.

The thread will run the cleanup function just before exiting. Use this function to delete the allocated source, close the port, or perhaps to transition to a different screen in your openal sound.

The reason for this is actually very simple, since it is an audio scene, one can perfectly want to stack up different sounds playing a different moments. The underlying implementation of alSourcePlay in OpenAL Soft actually spawns a openal sound thread as soon as you issue alSourcePlayso guess what happens in the following code snippet:. Instead, since we are doing this in a main thread openal sound example purposes, you must do the following:.

The orientation consists of two components, the general direction openal sound listener is headed at and rotation. Both are expressed as 3-value tuples for the x- y- and z-axis of the coordinate system. The orientation defines a orthogonal listening direction, so that any sounds the user or avatar hears, are processed correctly.
